Meh, we all know Mayhem was released for BS reasons. Cutting him for his poor performances would have made a hell of a lot more sense. Dana plays favourites with his fighters, and he does sometimes deserve to be called out on his blatant BS.
That said, Mayhem needs to let it go. No reason to dwell or get into online twitter wars. There's a way to go about these things, and needless to say this isn't it.
